The con­ver­sion the­ory has strong psy­cho­lo­gic­al effects.

The con­ver­sion the­ory explains why minor­it­ies can be power­ful bey­ond their numbers.

How does the con­ver­sion the­ory work?

Here we go:

The Conversion Theory

The social psy­cho­lo­gist Serge Moscovici found that we become more engaged if we belong to a mis­rep­res­en­ted minor­ity.

The dis­pro­por­tion­al power of minor­it­ies is known as the con­ver­sion the­ory. 1Conversion the­ory of minor­ity influ­ence. (2021, February 12). In Wikipedia. https://​en​.wiki​pe​dia​.org/​w​i​k​i​/​C​o​n​v​e​r​s​i​o​n​_​t​h​e​o​r​y​_​o​f​_​m​i​n​o​r​i​t​y​_​i​n​f​l​u​e​nce

“In groups, the minor­ity can have a dis­pro­por­tion­ate effect, con­vert­ing many ‘major­ity’ mem­bers to their own cause. This is because many major­ity group mem­bers are not strong believ­ers in its cause. They may be simply going along because it seems easi­er or that there is no real altern­at­ive. They may also have become dis­il­lu­sioned with the group pur­pose, pro­cess, or lead­er­ship and are seek­ing a viable altern­at­ive.”

How does it work?

The social cost of hold­ing a dif­fer­ent view than the major­ity is high. This increased cost explains why minor­it­ies often hold their opin­ions more firmly. It takes determ­in­a­tion to go against the norm. 3Moscovici, S. (1980). Toward a the­ory of con­ver­sion beha­viour. In L. Berkowitz (Ed.), Advances in Experimental Social Psychology, 13, 209 – 239. New York: Academic Press

In con­trast, many major­ity mem­bers don’t hold their opin­ions so firmly. They might belong to the major­ity for no oth­er reas­on than that every­one else seems to be. 4Chryssochoou, X. and Volpato, C. (2004). Social Influence and the Power of Minorities: An Analysis of the Communist Manifesto, Social Justice Research, 17, 4, 357 – 388

According to con­ver­sion the­ory, while major­it­ies often claim norm­at­ive social influ­ence, minor­it­ies strive for eth­ic­al high ground. 

Conversion Theory Examples

Given the power of norm­at­ive social influ­ence, minor­it­ies typ­ic­ally form tight-knit groups that can gath­er around a core mes­sage.

Most big shifts usu­ally start with a small group of ded­ic­ated people:

  • Dietary move­ments. A minor­ity advoc­at­ing for a spe­cif­ic diet or life­style choice (e.g., vegan­ism or paleo) gradu­ally per­suades oth­ers to adopt these prac­tices, lead­ing to a broad­er cul­tur­al shift.
  • Fashion trends. A small group of fash­ion influ­en­cers intro­duces a new style or cloth­ing item, and as they gain vis­ib­il­ity, the trend catches on and becomes widely popular.
  • Political act­iv­ism. Grassroots move­ments, such as cli­mate change act­iv­ism or social justice cam­paigns, can begin with a small group of pas­sion­ate indi­vidu­als who even­tu­ally influ­ence the wider pub­lic and bring about policy changes.
  • Workplace innov­a­tion. A minor­ity of employ­ees with­in a com­pany pro­pose a new strategy, product, or pro­cess that ini­tially faces res­ist­ance but even­tu­ally wins over the major­ity and leads to organ­iz­a­tion­al change.
  • Social media chal­lenges. Viral chal­lenges or trends often begin with a small group or an indi­vidu­al who cap­tures the pub­lic’s atten­tion, and the phe­nomen­on then spreads rap­idly to the majority.
  • Art and music appre­ci­ation. A minor­ity group, such as fans of an indie band or sup­port­ers of a con­tro­ver­sial artist, may ini­tially be seen as niche or uncon­ven­tion­al but can even­tu­ally bring their pref­er­ences into the mainstream.
  • Technology adop­tion. Early adop­ters of new tech­no­logy, such as elec­tric vehicles or crypto­cur­rency, may ini­tially be a minor­ity but can sig­ni­fic­antly influ­ence the broad­er pop­u­la­tion to embrace these innov­a­tions over time.
  • Educational reforms. A small group of edu­cat­ors or par­ents advoc­at­ing for changes in the edu­ca­tion­al sys­tem, such as altern­at­ive teach­ing meth­ods or updated cur­ricula, may sway pub­lic opin­ion and lead to wide­spread reforms.
  • Sports and fit­ness trends: New exer­cise routines or sports, like CrossFit or parkour, often start with a minor­ity fol­low­ing and, as their pop­ular­ity grows, influ­ence the lar­ger pop­u­la­tion to par­ti­cip­ate in and adopt these activities.
  • Language and slang. The evol­u­tion of lan­guage and the incor­por­a­tion of new slang terms or phrases can be traced back to minor­ity groups, such as spe­cif­ic sub­cul­tures or region­al com­munit­ies, whose lin­guist­ic innov­a­tions gradu­ally per­meate main­stream communication.

Minority Influence: A PR Approach

Organisations with CSR aspir­a­tions can cul­tiv­ate a sense of pur­pose and accom­plish­ment among par­ti­cipants by align­ing with a move­ment that chal­lenges a stu­pid majority.

Since we tend to favour under­dogs, liais­ing with a care­fully selec­ted minor­ity can be a game-chan­ging PR strategy.

Minority spokes­per­sons with sol­id con­vic­tions often pos­sess valu­able know­ledge and author­ity, enhan­cing their per­suas­ive abil­it­ies and influence.

Disproportionately, minor­it­ies can con­vert numer­ous major­ity mem­bers to their cause, as many in the major­ity may have merely fol­lowed the path of least res­ist­ance, made decisions without much con­sid­er­a­tion, or lacked viable alternatives.

Additionally, a sig­ni­fic­ant seg­ment of the major­ity might be dis­il­lu­sioned with their group’s pur­pose, pro­cess, or lead­er­ship, ren­der­ing them more recept­ive to altern­at­ive proposals.

Proceed With Caution, Please

As PR pro­fes­sion­als, we must be cau­tious when imple­ment­ing the con­ver­sion theory.

Minorities aren’t always right, and major­it­ies aren’t always wrong. Minorities can hold futile views while still exer­cising a dis­pro­por­tion­ate amount of power.

Backfire Effect (or “Belief Perseverance” or “Conversion Theory” or “Amplification Hypothesis”)

The back­fire effect (see also belief per­sever­ance, con­ver­sion the­ory, and amp­li­fic­a­tion hypo­thes­is) occurs when indi­vidu­als con­fron­ted with evid­ence that con­tra­dicts their beliefs or opin­ions become even more entrenched in those beliefs. Instead of adjust­ing their views based on new inform­a­tion, they react defens­ively and reject the con­tra­dict­ory evid­ence, often intensi­fy­ing their ori­gin­al stance.

Backfire effect (example): “I presen­ted sol­id data show­ing that the cur­rent mar­ket­ing strategy isn’t work­ing, but the team doubled down, insist­ing it’s the right approach and dis­miss­ing the data as flawed.”

In a busi­ness con­text, the back­fire effect can be highly det­ri­ment­al, pre­vent­ing organ­isa­tions from evolving and adapt­ing to chan­ging cir­cum­stances. By refus­ing to accept val­id feed­back or data that chal­lenges their assump­tions, teams may con­tin­ue down inef­fect­ive paths, wast­ing resources or miss­ing out on oppor­tun­it­ies for improvement.

To coun­ter­act the back­fire effect, busi­ness lead­ers should foster a cul­ture of intel­lec­tu­al humil­ity and open­ness, where feed­back is wel­comed and crit­ic­ally examined rather than rejec­ted outright. 

Encouraging a growth mind­set, where learn­ing and adapt­a­tion are pri­or­it­ised over being “right,” helps cre­ate an envir­on­ment where new ideas can be tested, and decisions are informed by evid­ence and reas­on. By pro­mot­ing open dia­logue and ensur­ing that evid­ence is eval­u­ated object­ively, organ­iz­a­tions can avoid the pit­falls of the back­fire effect and make more ration­al, data-driv­en decisions.

When con­fron­ted with a mir­ror of truth, many will look away to safe­guard the integ­rity of their ima­gined reflections.

The Stupid Majority PR Strategy

From what the con­ver­sion the­ory teaches us, minor­it­ies tend to hold their opin­ions more firmly. This is reas­on­able since going against the major­ity comes at a high­er social cost. 5Silfwer, J. (2017, June 13). Conversion Theory — Disproportionate Minority Influence. Doctor Spin | The PR Blog. https://​doc​tor​spin​.net/​c​o​n​v​e​r​s​i​o​n​-​t​h​e​o​ry/

But some minor­it­ies have an addi­tion­al advantage:

Smart minor­ity = a minor­ity of today that will grow into a new major­ity of tomorrow.

In con­trast, some major­it­ies have an addi­tion­al disadvantage:

Stupid major­ity = a major­ity of today that will stead­ily decline into a minor­ity of tomorrow.

Identifying a stu­pid major­ity (and sid­ing with a smart minor­ity) will cla­ri­fy your core mes­sage and attract highly engaged minor­ity supporters.

Examples of Stupid Majorities

Stupid major­it­ies are to be found everywhere:

  • “Riding a skate­board isn’t a real sport!”
    (Stupid Majority vs Red Bull)
  • “Computing is about bits and bytes, not design!”
    (Stupid Majority vs Apple)
  • “Streaming com­pan­ies can­’t pro­duce movies and tele­vi­sion shows!”
    (Stupid Majority vs Netflix)
  • “Electric cars can­’t com­pete with gas cars!”
    (Stupid Majority vs Tesla Motors)
  • “Hotels must have hotel rooms!”
    (Stupid Majority vs AirBnB)
  • “Taxi com­pan­ies must have tax­is!”
    (Stupid Majority vs Uber)
  • “Media com­pan­ies must pro­duce media!”
    (Stupid Majority vs Facebook)

Now, here’s the 1,000,000 EUR question:

What’s a stu­pid major­ity in your industry?

Challenging a Stupid Majority

Stupid major­it­ies exist in your industry, too. 

And now that you know what to look for, you’ll soon start find­ing them everywhere.

The stu­pid major­ity PR strategy could res­ult in the most pro­found res­ults of your pub­lic rela­tions career:

  • Identify a stu­pid major­ity in your industry.
  • Become a cham­pi­on for the oppos­ing smart minority.
  • Together, bring the giant down to a mighty fall!

Diffusion of Innovations

The dif­fu­sion of innov­a­tions the­ory, pro­posed by Everett Rogers in 1962, remains a frame­work for under­stand­ing how new ideas, tech­no­lo­gies, products, or prac­tices spread through soci­et­ies over time. 6Rogers, E. M. (2003). Diffusion of Innovations (5th ed.). Free Press.

Diffusion of innovations.
Diffusion of innovations.

The dif­fu­sion of innov­a­tions the­ory out­lines the pro­cess by which innov­a­tions are adop­ted by indi­vidu­als and groups, emphas­ising the role of com­mu­nic­a­tion chan­nels, social net­works, and the char­ac­ter­ist­ics of the innov­a­tion itself.

  • Innovators (2,5%)
  • Early Adopters (13,5%)
  • Early Majority (34%)
  • Late Majority (34%)
  • Laggards (16%)

The dif­fu­sion of innov­a­tions the­ory offers insights into how new ideas and tech­no­lo­gies influ­ence soci­et­ies. Understanding these dynam­ics can inform pub­lic rela­tions strategies across diverse contexts.

“Diffusion research has helped under­stand new product adop­tion and dif­fu­sion, with net­work ana­lys­is and field exper­i­ments being prom­ising tools in under­stand­ing the con­sump­tion of new products.”

Examples of Technological Adoptions

By examin­ing real-life examples, we can bet­ter com­pre­hend the prin­ciples of this the­ory and its applic­a­tions in vari­ous fields:

  • Smartphone adop­tion. The rap­id adop­tion of smart­phones provides a com­pel­ling example of the dif­fu­sion of innov­a­tions. Initially, smart­phones were adop­ted by tech enthu­si­asts and early adop­ters who val­ued their advanced fea­tures. Over time, as prices decreased and func­tion­al­ity improved, smart­phones became more access­ible to the gen­er­al pub­lic. Today, they are nearly ubi­quit­ous, illus­trat­ing the dif­fu­sion pro­cess from innov­at­ors to early adop­ters, early major­ity, late major­ity, and finally, laggards.
  • Social media adop­tion. The rise of social media plat­forms like Facebook, Twitter, and Instagram exem­pli­fies the dif­fu­sion of innov­a­tions in the digit­al realm. These plat­forms began with small user bases but quickly gained momentum as early adop­ters spread pos­it­ive exper­i­ences to their social net­works. As social media became ingrained in every­day life, more con­ser­vat­ive users gradu­ally embraced these plat­forms, lead­ing to wide­spread adop­tion across demographics.
  • Electric vehicle adop­tion. The adop­tion of elec­tric vehicles rep­res­ents a con­tem­por­ary example of the dif­fu­sion of innov­a­tions with­in the auto­mot­ive industry. Initially, EVs faced scep­ti­cism and lim­ited con­sumer interest due to con­cerns about range, char­ging infra­struc­ture, and price. However, as tech­no­logy advanced and envir­on­ment­al aware­ness grew, early adop­ters embraced EVs. Government incent­ives and improve­ments in bat­tery tech­no­logy fur­ther accel­er­ated adop­tion, lead­ing to broad­er accept­ance and main­stream adoption.
  • Streaming adop­tion. The shift from tra­di­tion­al tele­vi­sion to online stream­ing ser­vices illus­trates the dif­fu­sion of innov­a­tions in the enter­tain­ment sec­tor. Platforms like Netflix, Hulu, and Amazon Prime Video ini­tially attrac­ted tech-savvy early adop­ters seek­ing altern­at­ives to tra­di­tion­al cable TV. As these ser­vices improved their con­tent lib­rar­ies and user inter­faces, they gained trac­tion among the early and late major­ity. Today, stream­ing has become the dom­in­ant mode of con­tent con­sump­tion for mil­lions worldwide.
  • Telemedicine adop­tion. The adop­tion of telemedi­cine ser­vices provides a recent example of innov­a­tion dif­fu­sion in the health­care industry, par­tic­u­larly high­lighted dur­ing the COVID-19 pan­dem­ic. Initially met with scep­ti­cism due to con­cerns about patient con­fid­en­ti­al­ity and the qual­ity of care, telemedi­cine gained accept­ance among early adop­ters seek­ing con­veni­ence and access­ib­il­ity. As reg­u­lat­ory bar­ri­ers were over­come and health­care pro­viders integ­rated tele­health into their prac­tices, broad­er adop­tion fol­lowed, with patients and pro­viders recog­nising its benefits.
